I'm running RedHat 6.1. GNOME worked and continues to work (as well as it ever did). KDE WAS working and I broke it somehow. Now it seems that none of the buttons (icons) on the toolbar that run programs work any more. There is momentary disk activity when a button is pressed but nothing comes up. Buttons that bring up sub-menus still work inasmuch as the sub-menus come up, but when you finally reach an executable and invoke it nothing happens. None of the icons that used to appear on the desktop (templates, etc.) appear any more. There is a "kvt" terminal window that comes up and Netscape comes up. Both of them work; I can run programs from the kvt window. I have been messing around with the video and audio drivers recently. I am now using XF86_S3SAV instead of XF86_SVGA, and the "oss" sound drivers instead of nothing. I LIKE KDE! What did I do? Thanks, Ed.
